. . How are these Tissues protected? A delicate organ like the brain, which is so important for a variety of activities, needs to be carefully protected.
For this, the body is designed so that the brain sits inside a bony box. Inside the box, the brain is contained in a fluid-filled balloon which provides further shock absorption. If you run your hand down the middle of your back, you will feel a hard, bumpy structure. This is the vertebral column or backbone which protects the spinal cord.
